I will be getting my system installed next week. I recieved a well written proposal from the HVAC professional I chose from 5 estimates.
Any danger to me that he said I did not have to sign the proposal he would just mail me the bill when he was finished. He is a very casual guy and his company is well thought of, 85 year history in my area. Good references including one from from a fella I met at my kids soccer game who works for a HVAC distributor/supplier in my area who suggested him.
Thank you for providing me this forum to observe for the past month.
By the way he was the only one who came out and measured for a load calc. He also had the lowest btu furnace of the bunch.
